Lesser Invocation; 3rd
Make a touch attack against a living creature of your size category. If you succeed, your physical appearance (including garb) changes to match his, as disguise self.
In addition, when you use this invocation you can choose to bestow a –1d6 penalty to the touched creature's Charisma score. This penalty can't reduce the creature's Charisma below 1.
A successful Will save by the target negates both effects. A creature that successfully saves can't be affected by your mask of flesh for 24 hours.
Both effects last for 1 hour per warlock level; if you dismiss the invocation, both effects end.
